발표는 담뱃값인상과 수요탄력성에 대한 칼럼을 읽고 분석하고, 수요곡선의 개념과 가격의 탄력, 비탄력성에 대한 개념에 대해 설명해드리겠습니다. 그리고 이번 탐구의 핵심인 수요변화량에 대해 조사하고 이를 직접 식에 대입하며 미분으로 수요변화량을 어떻게 구할 수 있는지에 대해 탐구한 결과를 발표하겠습니다.

 

From now on, I will start my presentation with the theme of comparing price elasticity with differentiation.

First of all, I will read and analyze the column on cigarette price increase and demand elasticity, and explain the concept of demand curve, price elasticity, and inelasticity. And I'm going to investigate the amount of demand change that's at the heart of this exploration, put it directly into the equation, and present the results of exploring how differential changes in demand can be obtained. Lastly, I will present what I learned and what I need to supplement through this exploration.

 

First of all, the column we read this time is about the increase in cigarette prices and the elasticity of demand in Hankyoreh. First of all, the first paragraph says that the price of foreign cigarettes has risen. Demand for imported cigarettes has declined even though only a few items have been raised. On the other hand, the demand for domestic cigarettes, which are substitutes, has increased? This case is called the elasticity of demand. There are several factors that determine the magnitude of the elasticity of demand.

 

The first is whether there is a substitute or not. The domestic cigarettes that appeared in the first part of the column can be said to be a substitute for imported cigarettes. It can be said that the elasticity is high when products that are easy to replace are nearby. Secondly, we need to know whether it is a necessity or luxury item. Necessities are small in elasticity and luxuries are large in elasticity. The third is that the longer the demand gets, the more elastic it is. Finally, the wider the range of products, the less elastic the elasticity, and the smaller the product, the greater the elasticity.

 

To summarize the contents of the column so far, the sales of domestic cigarettes have increased due to the fact that they have not been loyal to certain cigarettes, making it easy to replace them with other cigarettes. By doing so, cigarettes are highly elastic products that can easily obtain alternatives. Paragraph 2 explains the elasticity of demand in earnest. Price elasticity of demand is a tool that measures the sensitivity of change in demand volume due to price fluctuations, and when prices rise, demand decreases, demand increases. At this time, the price elasticity of demand can be determined by dividing the rate of change in demand by the rate of change in demand.

 

Before I tell you what we've explored, let's look at the demand graph. Demand refers to a relationship that shows how much goods you are willing to buy within a certain time interval, or a desire or plan to buy goods. A graph in which demand decreases when prices rise is called a demand curve.

 

Elasticity is a figure of how shrewd sellers and buyers are to market conditions. Calculating how much the transaction volume changes when the price changes by A is the calculation of price elasticity. In contrast, inelasticity is a case where price elasticity is less than 1. For example, there are agricultural products, which are affected by nature and take time to produce, so rapid changes in supply are not easy.
